During classified visits, which system is used to supply clearance information?

• A. The DOD personnel security system of record
• B. A hard copy form
• C. The NISPOM database
• D. The GCA portal

Answer: (A)

The main idea is that the clearance status checked for a classified visit comes from the DoD personnel security system of record. This is the official repository for active clearances and access approvals, kept up to date by adjudicative decisions and security offices. Facilities rely on it to verify that a visitor has the required clearance level and any necessary access authorization before granting entry. Relying on a hard copy form is unreliable and prone to being outdated, and the NISPOM database or the GCA portal aren’t the designated live sources for clearance information used at entry points. Using the DoD personnel security system of record ensures the information you’re using is current and authoritative.
